- ---- --------- -------------- ------------------------------------
- c1 30 Mar 92 M. Adler explode that uses huft_build from inflate
- (this gives over a 70% speed improvement
- over the original unimplode.c, which
- decoded a bit at a time)
- c2 4 Apr 92 M. Adler fixed bug for file sizes a multiple of 32k.
- c3 10 Apr 92 M. Adler added a little memory tracking if DEBUG
- c4 11 Apr 92 M. Adler added NOMEMCPY do kill use of memcpy()
- c5 21 Apr 92 M. Adler added the WSIZE #define to allow reducing
- the 32K window size for specialized
- applications.
- c6 31 May 92 M. Adler added typecasts to eliminate some warnings
- c7 27 Jun 92 G. Roelofs added more typecasts

- Explode imploded (PKZIP method 6 compressed) data. This compression
- method searches for as much of the current string of bytes (up to a length
- of ~320) in the previous 4K or 8K bytes. If it doesn't find any matches
- (of at least length 2 or 3), it codes the next byte. Otherwise, it codes
- the length of the matched string and its distance backwards from the
- current position. Single bytes ("literals") are preceded by a one (a
- single bit) and are either uncoded (the eight bits go directly into the
- compressed stream for a total of nine bits) or Huffman coded with a
- supplied literal code tree. If literals are coded, then the minimum match
- length is three, otherwise it is two.
-
- There are therefore four kinds of imploded streams: 8K search with coded
- literals (min match = 3), 4K search with coded literals (min match = 3),
- 8K with uncoded literals (min match = 2), and 4K with uncoded literals
- (min match = 2). The kind of stream is identified in two bits of a
- general purpose bit flag that is outside of the compressed stream.
-
- Distance-length pairs are always coded. Distance-length pairs for matched
- strings are preceded by a zero bit (to distinguish them from literals) and
- are always coded. The distance comes first and is either the low six (4K)
- or low seven (8K) bits of the distance (uncoded), followed by the high six
- bits of the distance coded. Then the length is six bits coded (0..63 +
- min match length), and if the maximum such length is coded, then it's
- followed by another eight bits (uncoded) to be added to the coded length.
- This gives a match length range of 2..320 or 3..321 bytes.
-
- The literal, length, and distance codes are all represented in a slightly
- compressed form themselves. What is sent are the lengths of the codes for
- each value, which is sufficient to construct the codes. Each byte of the
- code representation is the code length (the low four bits representing
- 1..16), and the number of values sequentially with that length (the high
- four bits also representing 1..16). There are 256 literal code values (if
- literals are coded), 64 length code values, and 64 distance code values,
- in that order at the beginning of the compressed stream. Each set of code
- values is preceded (redundantly) with a byte indicating how many bytes are
- in the code description that follows, in the range 1..256.
-
- The codes themselves are decoded using tables made by huft_build() from
- the bit lengths. That routine and its comments are in the inflate.c
- module.
